The Hydra uses SpiritsUp.
|User||Hydra, Terrator, WightKnight|
|Description||Increases physical defense|
SpiritsUp (気合い , Kiai, lit. Fighting Spirit?) is a Yellow Enemy Tech used by the Hydra, Terrator and the WightKnight in Chrono Cross . This tech allows its user to summon a shield, which showers yellow sparkles on said user to temporarily raise its defense.
A translucent diamond-shaped shield will first appear in front of the user. It will promptly vanish, showering the user in yellow sparkles. A message announcing the increase in the user's defense will then flash across the screen.
